A blockchain-based approach to the challenges of EU’s environmental policy compliance in aquaculture: From traceability to fraud prevention

In light of the current global scenario, regulatory requirements, and stakeholder expectations for the aquaculture supply chain are more demanding than ever. The latest EU strategies for aquaculture aim to ensure its economic, environmental, and social long-term sustainability through green, technological, and social transformations. This objective is as ambitious as it is complex, involving not only the enhancement of key sustainability aspects but also the assurance of transparency, trust, and security standards across the entire supply chain. In this context, the present paper proposes a novel blockchain framework, along with the strategic implementation of smart contracts, specifically designed to effectively address the prevalent environmental challenges within the aquaculture supply chain.
